Zone 5a planting calendar
In USDA hardiness zone 5a, the average last spring frost is around April 30 and the average first fall frost around October 5: a growing season of about 158 days. Here is when to start seeds, plant, and harvest 157 vegetables, fruits, herbs, and flowers.
Zones measure winter cold, not frost dates, so these are regional averages. Frost-tender crops wait until about May 14, when a late frost is unlikely.
